Australia: Close up of Red Bulldog Ant (Myrmecia gulosa), also known as the giant bull ant, perched on a branch looking in the distance. It is one of the largest ant species being known to grow up to 30mm in length. The head and thorax are typically red-brown in colour with a black rear abdomen and yellow-brown pincers (mandibles). These pincers can deliver a nasty bite, causing severe pain for a couple of days. This image is from World's Weirdest Animal Faces.

Africa: Flap-Necked Chameleon (Chamaeleo dilepis), poised on top of a tree branch in tropical Southern Africa. These species vary widely in colour, from various greens, yellows and browns. Flaps on their neck usually lie flat, however when they feel threatened they can be raised and angled at 90 degrees to the head to ward off predators. This image is from World's Weirdest Animal Faces.
